The Tenacious is an extremely popular multipurpose, go anywhere, do everything, everyday carry knife from Spyderco! It's a mid sized reliable, and durable, liner lock knife that is as tough as nails. It starts with a highly functional leaf shaped 8Cr13Mov stainless steel drop point blade and a black G-10 handle. The handle fills the hand like a much larger knife and provides a rock solid grip even in the worst environments. The 8Cr13Mov blade is 3.4" of partially serrated cutting aptitude with a cusp on the blade's spine to naturally position the thumb in control over the sharp edge. Blade and handle geometry create a variety of grip angles and leveraging points so when held and used the knife feels and reacts like an extension of the hand. Even the position of the Spyderco Round Hole, relative to the pivot, is precise for smooth opening, hitting all the correct pressure points in the hand ergonomically. It has and reversible ambidextrous tip-up tip-down pocket clip so it's ready to go with you everywhere. The Spyderco Tenacious is the EDC blade that's ready to help you take on your next challenge!
